A simple to use and flexible image manipulation symfony plugin. The plugin allows you to perform "transforms" on an image. A transform maybe simple like a resizing or mirroring or more complex like overlays and pixelizing. The transforms can be chained together or applied individually. New transforms can be simple created by extending the sfImageTranform abstract class.

A simple to use and flexible image manipulation symfony plugin. The plugin allows you to perform "transforms" on an image. A transform can be simple like thumbnailing, resizing or mirroring or more complex such as adding watermarks and pixelizing. The transforms can be chained together or applied individually. New transforms can be simply created by extending the sfImageTranform abstract class. GD and ImageMagick are both suppported

sfImageTransformPlugin

The sfImageTransformPlugin allows the easily manipulation of images. The plugin requires either either GD or ImageMagick graphics libraries to be installed on the server.

sfImageTransform works by applying one or more "transforms" to the image. A transform maybe simple like resizing or mirroring or more complex like overlays and pixelizing. Multiple tranforms can be easily applied by chaining the transform calls as seen below. It is also very easy to extend and create your own transforms.

Load an image, resize it to 100 pixels wide (preserving the aspect ratio) and rotate it 90 degrees:

Writing your own transforms

sfImageTransformPlugin is designed to be easily extended. To make a new transform you simple create a class that extends the abstract class (sfImageTransformAbstract) and implements the transform method.

Transforms are written specifically for the image library you want to use or generically if they don't use image library specific calls (see the thumbnail transform).

The naming convention for a transform is important. For generic transforms the class should be named sfImage#transform name#Generic and for graphic library specific transforms, sfImage#transform name##image library#.class.php and class names should be sfImage#transform name##image library#

Let's create a GD transform called "Example".

sfImageExampleGD.class.php

class sfImageExampleGD extends sfImageTransformAbstract
{
// Parameters can be passed in the standard way
public funnction __construct($arg1, $arg2)
{
...
}
public function execute(sfImage $image)
{
// Get the actual image resource
$resource = $image->getAdapter()->getHolder();
// Manipulate image using the GD functions
...
// To set a new resource for the image object
$image->getAdapter()->setHolder($dest_resource);
}
}
